EPA delays enforcement of levels set for PFOA and PFOS, and rescinds them for four other PFAS
The Trump administration has rolled back the US’s first legally enforceable national drinking water limits for six per- and polyfluoroalkyl substances (PFAS), which were established in April 2024 under former President Biden. There was an outcry among researchers in the field, as well as environmental advocates, following the announcement.
The Environmental Protection Agency (EPA) announced on 14 May that it had delayed these national drinking water regulations for the two most well-known of these substances – perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) – and was repealing them for four other PFAS.
